Hi there, Once again, sorry if my question seems childish. Can someone explain to me what is behind gateways, shared storage and what is the benefit of using things like hadoop plugin ? Is there a documentation about this ? PS : you probably know but most of the documentation links found on google are broken thks ---

The gateway concept allows for long term persistency of the cluster (state + indices). Explained here: [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/modules/gateway/). The two main types are the local gateway, allowing ot recover the state of the cluster using the local storage of each node. And a shared gateway (shared file system, hadoop, s3) which can store the data in a remote storage that is accessible to all data nodes.
